/**
 * Map Marker Details Drawer Styles
 * Theme-aware styling matching map-filter.css design language
 * Deterministic positioning - always viewport-anchored
 *
 * ARCHITECTURE: The drawer elements are moved to document.body by JS at init
 * time. This escapes any ancestor containing blocks (e.g. #main-content with
 * will-change:transform, #map-container with transform:translateX(-50%)) that
 * would break position:fixed. The JS positionOverlay() function calculates a
 * viewport-clamped top value on desktop; on mobile, CSS handles the bottom-sheet.
